What is the amplitude, period, and phase shift of f(x) = −2 sin(3x − π) − 1?
amplitude = 2; period = two times pi over three; phase shift: x equals pi over three
amplitude = −2; period = 2π; phase shift: x equals pi over three
amplitude = 2; period = two times pi over three; phase shift: x equals negative pi over three
amplitude = −2; period = 2π; phase shift: x equals negative pi over three

Amplitude = 2; period = two times pi over three; phase shift: x equals pi over three

Step-by-step explanation:

The given function is

Comparing to , we have a=-2 , b=3, and d=-1.

The amplitude is .

This implies that amplitude is

The period is

This implies period is

The phase shift is

This implies that phase shift is

y + 11 = (1/4)(x + 16)

step-by-step explanation:

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
